Clearing Diagnostic Trouble Codes

DTCs can be cleared using scan tool. If scan tool is not available, turn ignition switch to OFF position. Remove PCM fuse from fuse block for 30 seconds. Replace fuse. DTCs may also be cleared by disconnecting negative battery cable. However, this may result in loss of other on-board memory data, such as preset radio tuning. After power to PCM is removed, poor driveability may occur until PCM "relearns" operating parameters.

DTCs will be cleared under the following conditions: PCM will cancel DTC default actions when fault no longer exists and ignition is cycled off long enough to power down PCM. DTC will be cleared when vehicle has achieved 40 warm-up cycles without failure reported.
